Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during the repair.

2. Inspect and Replace Bulbs

Tools Required: Screwdriver set, gloves
Remove the fog light assembly from the vehicle by unscrewing the retaining screws.
Disconnect the wiring harness from the fog light bulbs.
Remove the bulbs from the assembly and inspect for any signs of damage.
Replace with new bulbs if necessary; ensure the same type is used (usually H11 for G70).
Reconnect the wiring harness and secure the fog light assembly back into place.

3. Check and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box (usually found under the dashboard or in the engine compartment).
Identify the fog light fuse using the diagram on the fuse box cover.
Pull the fuse and inspect it for continuity; replace with a new fuse if blown (typically 15A).
Reinstall the fuse and close the fuse box.

4. Test Fog Light Switch

Tools Required: Multimeter
Locate the fog light switch on the dashboard.
Use a multimeter to test for voltage at the switch when activated.
